Eric and pam are paid $48.75 for their work. Eric worked 2.5 hours, and pam worked 4 hours. They split the money according to the amount of time each of them worked. How much is erics's share of the money? Explain.
Answer:
$18.75
Step-by-step explanation:
Determine the total hours worked by both individuals = 2.5 + 4 = 6.5 hours
Determine the fraction of hours that Eric worked = 2.5/6.5 = 0.384615
Multiply this fraction by the total amount earned = 0.384615 x $48.75 = $18.75

The area of a circle is 201 square meters. Find
the radius.
Answer:
8.0meters
Step-by-step explanation:
Given data
Area of cirlce= 201 square meters
The expression for the area is
A=πr^2
Substitute our area
201= 3.14*r^2
r^2= 201/3.14
r^2= 64.01
square both sides
r= √64.01
r= 8.0 meters
Hence the radius is 8.0meters

This formula is used to calculate the area of a circle using the diameter:
A= 1/4πd².
Rearrange the formula to calculate the diameter of a circle.
d = _____
Answer:
d= 2√a/π
To calculate the diameter, rewrite the formula to isolate D
Because a negative diameter doesn’t make sense, eliminate the negative answer from the solution
Simplify further to get the solution
The formula to calculate the diameter of the circle is d = 2 √( A/π )
where d = diameter of the circle
A = area of the circle
What is a Circle?
A circle is a closed two-dimensional figure in which the set of all the points in the plane is equidistant from a given point called “center”. Every line that passes through the circle forms the line of reflection symmetry. Also, the circle has rotational symmetry around the center for every angle
The perimeter of circle = 2πr
The area of the circle = πr²
where r is the radius of the circle
The standard form of a circle is
( x - h )² + ( y - k )² = r²,
where r is the radius of the circle and (h,k) is the center of the circle
Given data ,
Let the radius of the circle be = r
So , the diameter of the circle = 2r
Now , the area of the circle = πr²
Substituting the value for r , we get
Area of the circle = ( 1/4 ) πd²
So , A = ( 1/4 ) πd²
Now , solving the equation for diameter of circle d , we get
Multiply by 4 on both sides of the equation , we get
πd² = 4A
Divide by π on both sides of the equation , we get
d² = 4A/π
Taking square roots on both sides of the equation , we get
d = 2 √A/π
Therefore , the value of d is 2 √A/π
Hence ,
The formula to calculate the diameter of the circle is d = 2 √( A/π )
where d = diameter of the circle
A = area of the circle

Given 300mL of a gas at 17.0 degrees Celsius, what is the volume at 10 degrees Celsius if the pressure remains constant?
Answer:
292.75mL
Step-by-step explanation:
From the ideal gas equation
PV= nRT
With each symbols having standard meaning
For pressure remaining constant the equation for two states can be written as
[tex]\frac{V_1}{T_1}=\frac{V_2}{T_2}[/tex]
Given V_1 = 300mL, T_1 = 17° C = 290K and T_2 = 10°C or 283K
Now plugging values in above equation to find V_2
[tex]\frac{300}{290} =\frac{V_2}{283}\\V_2 =\frac{300}{290}\times283 = 292.75mL[/tex]
Therefore, the volume at 10 degrees Celsius = 292.75mL

Sum of interior angles of a quadrilateral is 360°
110° + 130° + x + x - 3° = 360°2x = 360° - 237°2x = 123°x = 61.5°(18)
Sum of interior angles of a hexagon is 180°*(6 - 2) = 720°
2*90° + 2x + 2(x + 22°) = 720°90° + x + x + 22° = 360°2x = 360° - 112°2x = 248°x = 124°(19)
Interior angles of a given pentagon are all marked as congruent, so the exterior angles are congruent too.
Sum of exterior angles is 360°.

Answer:
I think you wrote something wrong.
Step-by-step explanation:
If Alaina has $7 in her bank account and Joel had $48 in his Joel already has more then Alaina but I will attempt to teach you how to solve these types of problems.
for this example I'm giving Alaina 79 dollars.
First we know were starting with 79 dollars and increasing 6 dollars each day so the equation for this is; y = 6x + 79 that is Alaina's equation.
For Joel our equation will be; y = 8x + 48.
Since they already have 79 and 48 dollars in their bank we put those as our B in the equation cause they are our y-intercepts. (Y = mx + b) Next we know their increasing by 6 and 8 dollars a day so we make those our m. Once we have these equations we can plot them and see where the lines meet. (thats our answer) I plotted them on desmos graphing calculator.
They crossed at (15.5, 172) Which means it will take 16 days for Joel to catch up they will both have 172 dollars in the bank account on the 16th day.

1. When Aaron runs the 400 meter dash, his finishing times are normally distributed with a mean of 80 seconds and a standard deviation of 2.5 seconds. Using the empirical rule, determine the interval of times that represents the middle 99.7% of his finishing times in the 400 meter race.
Answer:
(72.5,87.5)
Step-by-step explanation:
The interval of times that represents the middle 99.7% of his finishing times in the 400 meter race is; (73.5, 87.5)
What is the interval from empirical rule?
We are given;
Mean; E(X) = μ = 80 seconds
Standard Deviation; σ = 2.5
From the empirical rule, the probability of obtaining values within one deviation from the mean is 0.68; within two deviations is 0.95 and within 3 deviations from the mean is 0.997.
We have 99.7 % of the values within 3 deviations from the mean in our question and so the intervals are;
μ - 3σ = 80 - 3(2.5) = 73.5
μ + 3σ = 80 + 3(2.5) = 87.5
